A fighter looks gaunt in a photo and fight week fills with certainty. MMA weight cut news is mostly claims, and claims are not evidence. You will learn to rank sources, keep three timelines apart (camp, official weigh-in, fight-day readiness) and log the exact time of every update, including corrections. A worked example takes a 54% baseline, applies a rumor-driven drop to 49%, and insists you report the two numbers separately, because the adjustment was never measured. Photos and gossip make weak proxies for how a fighter will perform. Use an evidence ladder, and change a model only when a result from an official source or a calibrated history backs the change.
Learning objectives
- Explain the relevant technique and distinguish observations from assumptions.
- Reproduce the worked example independently.
- Identify conditions when uncertainty invalidates an apparent edge.
